Last time I tried the App, it only supported segwit addresses (addresses beginning with 3).
Now I see it has greatly improved, especially adding the Native Segwit and Liquid Network.
Also listed in the the bitcoin.org wallet list.

As far as UI/UX go, it's probably the top mobile wallet in all of bitcoin (just my opinion). I have the desktop version for Linux.
Yep, its the mobile wallet i have found easiest to use for on-chain and it can use liquid as well which is nice. Soon it will have lightning support and may be a true 'one stop shop' for a wallet.
Yep have used - available on all mobile and desktop platforms, along with support for both bitcoin and liquid. Simple wallet setup guide here:
